Crash on server minecraft 1.7.10

[_Lightning_]

Hello, I noticed that even if the client and the server should have the same mods, when I try to login from the client the server crash this way:

anyone has any idea how I could identify the mod related with this problem?

Excepting testing them one by one...

to be honest, the modpack is based on Terrafirmacraft..  I don't think I can find terrafirmacraft on version 1.9 or 1.10..

and this apply on various mods still, interesting mods also...

Honestly, I can't blame modders that want not update their mods, Mojang can't force other people to stay behind the continuous updates choice... I know that Lex Manos doesn't approve, but he should understand that not every modder have the same time he has to update and re-write their content only because there is a more recent version of the game every 3-4 months..

What I'm also tryng to say is that is VERY dispersive tryng to catch with the Mojang update. All the good contents, many of good mods remain behind.

It is more wise that the Forge team and the entire community choose universally a version of the game to focus on, and stay there for 4-5 years more or less, and so on, because despite the interesting news that Mojang can bring in, it's very dispersive and destructive for the community, tryng to catch a Train that never stops.

Surely not, it's not up to me, I'm only reporting a thought that is very common in the minecraft community, expecially in modding
